Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Beef Roll
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the filling
Chop the bread, round steak, and salt pork finely.
Season with salt, pepper, and a little chopped onion.
Mix with the beaten egg.
Roll the mixture in a sheet of buttered parchment paper.
Bake and make the gravy
Bake at 350°F (175°C) for 1 hour.
When juices begin to ooze, add a little water to the pan to prevent burning.
Add a little tomato and butter to the gravy and thicken.
Pour the gravy over the meat or serve separately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Round steak
- Forms the main body of the roll and provides the meaty flavour and structure.
- Egg
- Binds the chopped mixture together so it holds its shape when rolled and baked.
- White bread
- Absorbs juices and adds softness, helping the filling stay moist.
- Salt pork
- Adds fat that keeps the filling moist and adds savoury flavour as it cooks.
- Tomato
- Adds acidity and colour to the gravy.
The step that matters
Adding water when juices begin to ooze. Meat juices that reach the pan can scorch as they concentrate. A small amount of water loosens the drippings and slows burning, which keeps the gravy from tasting bitter.
Swap the onion
How well each one fits the dish's main ingredients (pork, egg, bread, pepper, butter, tomato):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against pork, egg, bread, pepper, butter, tomato. Candidates are from the same food group and used in at least 100 recipes.
